Dietary reference Values for the different types of sugars have been set, partly based on the differences in cariogenicity between intrinsic and non-milk extrinsic sugar. However little information is available about the usual intake of these different sugars in population groups in the UK. Using a large Scottish data base, and food frequency questionnaire information on usual dietary intake, the values for mean daily intakes of intrinsic, non-milk extrinsic and milk sugars have been estimated by sex, age (range 25-64 years), special diet, smoking habit, body mass index and social class. The data are presented as g/day and as a percentage of total energy intake so that they may be viewed in context to the recommendations, particularly for non-milk extrinsic sugar intake. The results illustrate that low total or non-milk extrinsic sugar intakes are not necessarily associated with good health since men as a whole fail to meet the recommendation of less than 10% energy from non-milk extrinsic sugar, while women as a whole do, and obesity is associated with low sugar intakes. This emphasizes the need to consider all the nutrients in a diet together, before assessing its likely 'healthiness'.
